The numeral I marks'one jambof a doorway, `carrying' an .abutment strip A2. The opposite jamb of the doorway is marked bythenumeral 3 5 and carriesan abutment strip #provided-with an angular wear platei'i. A; door 6 is hingedat lfto the `jarnby IA and closes againstthe'abutment` strips Zandl. l VThe `numeral 8 designates' an :elongated 1 box- 40 like casing, preferably made of metal. The casy ing 8 is closed at both ends, at the'front and-at the top, but is openat' the backandat the bot-` tom'.v The casing 8 has `an upstanding'iiange-"SJl farmsl 29 ofthe bell crank. lever'28zare. pivotally adapted toreceive securingelements I0 whereby 45 the casing 8 is fastened to the' doorA 6'. Thecas-Y head 3l 4is secured toon'e `end of the operating ing 8 is supplied at its ends with flanges I1 which,

also, are secured to the door 6^.' In order to makeV tudin'ally of the operating.v member 32, and with this enclin view, thehead 31 has an elongated the casing 8 longitudinallyA adjustable tot doors of different widths, the casing-is composed* of other, as shown at H.

of `'the ange 9' are overlapped oneach other.

One of said ends ofthe ange 9 'carries a clamping device; such as abolt I5, adjustablein a slot I6 in the other part of the ange, as` shown in 1'. `.Without furtherv description, it wi11be,5 lfunderstoodthat thev casing 8 is adjustableas to length. if,

In its ends, and close tothe door V6-the casing' x8 vis'supplied with slots yll receiving the reduced ends20 of a closuramember I9, preferably m10 ,the -form of a plate,.slidable'in contact with the door 6, vertically. ,.The closure. member. I 9 is made in two parts which are overlapped on each other, so that the closureplate, like the casing 8,-

-may be adjusted as'to length. Onefpart of the 15- .closure member lI9 carriesa clamping device or bolt 2l, adjustable in a slot 2,2, in the other part 'ofthe'closureplate.-v x f IFixed horizontal tracks.4 23, 4which' may Ibe angle members, are secured to the'closure plate 20 I9 near to the endsthereof. Below `the tracks 23 are disposed spring tongues24, 'each `of which is secured at one end, as shown at 25to the closure plate I9. The front vwall-of the casing 8 .carries rearwardly projecting brackets 2li,l 25 whereon depending' bellcranks 28' are fulcrumed Each member 32,preferably made in two parts, so that itvcanrbe adjusted as to length, ylike the casing 8 35 andtheclosure plate I9.A One ofthe parts of the operating member 32.-is supplied at its innerend with asocket 34,`in which'the 'corresponding end ofthe other vpart of the I"operating'member is' received for longitudinal adjustment. said other 40 part of the operatingmember `32 carries a 'clampelongated slot; 35'in the socket 34;. The second mounted at 33'in the operating member 32. A 45 member 32. 'Ihe head 31 isadjustable `longiinthe head 3l. Theopposite kend ofthe link ofthe other part of the casing. The inner end'sxi Allis pivotally mounted at '42 in one arm of a 55 of the spring bearing against `the outer wall ofV the casing S. `The function of. the spring 41 is to swing the actuatingV lever 43 outwardly through the opening 46 in the end of the casing 8, when the door 6 is opened from the position shown in Fig. 1.

The device will operate regardless of whether the left hand edge or the right hand edge of the.

door is the hinged edge. A comparison of Figs.

2 and 5 will make manifest the correctness of the foregoing statement.

In practical operation,Y when the door 5 is closed, as in Fig. `1, the actuating lever 43 engages the wear plate 5 on theabutment strip` 4, and the actuating leverV is swung on its fulcrum shaft 44.

The actuating lever 43 operates the linkllih thef operating member 32 is carried to the right, and"` the'bellcrank levers 28 are'swung on their fulcra 217 the rollers 3| on the second arms 38 of the bell crank levers 28 carryingthe closure member I9 downwardly to the position of Fig. 3, and holding it in` that position yieldably, because the` spring tongues `24 areV flexed by the operation of the rollers 3i on the second arms 30 of the bell crank levers.`

' When the door E opened, the actuatingiever 43 no longer is pressed against the wear plate 5 oni the door frame, and the actuating lever swings to the leftin Fig.v 1, under the impulse of the spring 41. The link 40 Aimparts longitudinal movement to the operating member 32 to the leftv 'in Fig, 2, the rollers'Sl' on the arms 30 of Vthe;

bell'crank levers 23 engage the tracks 23 on the closure member i9, and the closure member is raised.

Because the closure plate I9 has reduced parts i 20, which extend outwardly through the slots i3 in the ends of the casing 8, thereduced parts 2li overlap the abutment strips 2 lvand4, and practically close thespaces between the ends of the casing 8 andv the abutment strips, the construc- Y tion having a manifest'advantage over one in which the closure plate works entirely within the casing, the aforesaid spaces being left opened.

It isto be observedthat the closure plate I8 is located at the 'extreme back 4of the casing 8, in Acontact with the door 6, andas far as possible from the outer wall of the casing 8, as Fig. v3 will show. Itis at the outer wall of the casing *8 that snowand ice collect, but the closure plate I9 is set far enough backfrom the outer wall of the casing 8 so that snowand iceare not likely to collect against the lower part of the closure plate and freeze it fast to the threshold. 'y

In assembling the-device, the actuating lever '43 shouldproject out of the end of the casing 8 the proper amount, andat the same time. the

lower edgev of the closure plate I9 ought to be positioned properly with respect to the lower edge of the door 6. In order to obtainA this relation,

there has to be expended in the making of similar articles, a degree of accuracy not protable in connection with a cheap article of the class described. The difficulty is circumvented by maky:ing the head 31 adjustable longitudinally of the operating member 32. n

A reason has been set forth hereinbefore for having the'closure plate I9 set well back from the outer wall of the casing 8, and it is not practical to lengthen the horizontal part of lthe bracket 26 and put the bell crank 28 between the track 23 and the spring tongue 24, because if that 'were done, the angle of the bell crank would have to be increased 'to practically 180 degrees, and

such a bell crank or lever would not function y properly. Since the bell crank 28 has to be located to one side ofthe track 23 and the spring tongue 24, asshown in Fig. 3, the bell crank has to be provided with-the laterally and inwardly extended nger |00, whereon the roller 3| is ijournaled.v If fitwere possible to' place the bell crank lever .28 between thetrack23 and the springtongue T24, the: track 23 could be replaced rby a mere projection or pin,since such an ele-` ment could ride lalong one arm of the bell crank. Considering, however, the fact that the bell crank lever 28 has to have theilnger |00, a projection lor pin,- used in place ofthe track 23';

would have to berloca'ted with considerable ac-` curacy, No such accuracy is needed when the elongated track 23 is used. i i y Havingthus described the invention, what is 'claimed is: y

v 7' In av` device of the'class described, a casing iny cluding fa front wall-and end walls, the

end walls having vertical slots in their lower edges, a

'closure-provided at its lower corners with reduced parts. `extending outwardly through the `slots to bridge the spaces between the end walls ofA thecasing Vand the jambs of a door frame, the

closure being located at the extreme back of the casing, wherebythe' front wall of the .casing will constitute .awea'therV-stop for the closure and les-r sen thechance of the ylower edge of the closure freezing. to a threshold, anl elongated track cai-v ried by the` closure and' extended longitudinally thereof,l aspring carried by the closure and eX- tended`longitudinally.thereof, the spring being yloca'tedbelow the track and `being spaced from the tracljg'fa'nv operating member movable longi' .tudinally of the casing, a bell crank lever fulcrume'd on the" casing in front of the track and Ifthe spring, means for pivotinglone arm of the bell' crank lever to the operating member, means cooperatin'g'with the spring to depress-the closure yieldably and cooperating with the track to raise the closure positively, the last-specified means` comprising. a laterally `prolonged finger-.on the other arm of the bell crank lever and extended Vbetween thespringland the track, ajamb-en- Igaging'lever fulcrumed onvone end of the casing,
